VLAN Configuration Examples

A VLAN is an administratively configured LAN segment that limits the traffic in multiple broadcast domains. Instead of
physically reconnecting a device to a different LAN, network administrators can accomplish this task by configuring a
VLAN compliant switch to create logical network segments.
Tagged VLAN allows switch segmentation to span across multiple managed switches. This type of VLAN is ideal for
LANs that consist of various types of communication groups such as Office LANs, Controls Systems, and IP
Cameras. When used properly, it will effectively isolate two or more groups from each other in a logical manner. This
means that Broadcast, Multicast, and Unicast frames in one VLAN will not interfere with another isolated VLAN group.
The examples in this section are shown as configured on a 708TX switch, but the 7506GX2 may be configured
similarly with changes in ports.
